Intravenous Immunoglobulin for Congenital Parvovirus Myocarditis
Congenital parvovirus infection has a diverse presentation ranging from asymptomatic infants to intrauterine demise secondary to red cell aplasia or myocarditis. Treatment is aimed at correcting anemia with intrauterine and postnatal transfusions. We report a case of fetal hydrops with severe atrioventricular regurgitation and myocardial dysfunction secondary to parvovirus infection in a preterm infant. Myocarditis and myocardial dysfunction responded to immunoglobulin administration.12 month embargo; published online: 18 January 2018This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Elevated Coefficient of Variation in Total Fecal Bile Acids Precedes Diagnosis of Necrotizing Enterocolitis
Accumulation of bile acids (BAs) may mediate development of necrotizing enterocolitis (NEC). Serial fecal samples were collected from premature infants with birth weight (BW) = II NEC were matched with control infants based on BW, EGA, day of life (DOL) enteral feeding was initiated and DOL of the first sample. From each subject, five samples matched by DOL collected were analyzed for BA levels and composition. Fifteen individual BA species were measured via LC-MS/MS and total BA levels were measured using the Diazyme Total Bile Acid Assay kit. No statistically significant differences in composition were observed between control and NEC at the level of individual species (p = 0.1133) or grouped BAs (p = 0.0742). However, there was a statistically significant difference (p = 0.000012) in the mean coefficient of variation (CV) between the two groups with infants developing NEC having more than four-fold higher mean CV than controls. Importantly, these variations occurred prior to NEC diagnosis. These data suggest fluctuations in total fecal BA levels could provide the basis for the first predictive clinical test for NEC.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
